Air Permeability and Water Vapor Resistance of Differently Finished Cotton and Cotton/Elastane Single Jersey Knitted Fabrics
(Taylor and Francis Ltd., 2022)
This study investigates the knitted fabrics' air permeability and water vapor resistance as complex phenomena of the interaction between the fiber nature, fabric structural characteristics and, different wet processes. ...
Enhanced Antimicrobial Activity of Atmospheric Pressure Plasma Treated and Aged Cotton Fibers
(Journal of Natural Fibers, 2022)
In this work, plasma pretreatment of raw cotton fibers combined with silver sorption was used for the preparation of antimicrobial fabrics. Special attention was given to the aging effect investigated seven days after ...
Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application
(Elsevier Ltd, 2022)
An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles ...
Novel eco-friendly initiation system based on vitamin C for energy efficient synthesis of PMAA hydrogel used for delivery of phenolic compounds
(Elsevier B.V., 2023)
This study reports successful free radical synthesis of pH-sensitive hydrogels based on poly(methacrylic acid) (PMAA) by using new green initiation system based on vitamin C and hydrogen peroxide (VC/H2O2). The application ...
Acetylation of cellulose – Another pathway of natural cellulose aging during library storage of books and papers
(Elsevier Ltd, 2022)
Gaseous acetic acid is formed under conditions of storage of historic paper objects. Its presence not only promotes hydrolytic cleavage of cellulose, but also causes acetylation of the cellulosic material to very small ...
Effect of chemical modifications and coating with Cu-based nanoparticles on the electro-physical properties of jute fabrics in a condition of high humidity
(Elsevier B.V., 2022)
The electro-physical properties of raw, alkali and oxidatively modified jute fabrics were investigated as complex phenomena of the interactions between the fabrics’ chemical composition, carboxyl group content, crystallinity, ...
The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(Journal of Natural Fibers, 2022)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Steroid-based tracing of sewage-sourced pollution of river water and wastewater treatment efficiency: Dissolved and suspended water phase distribution
(Elsevier B.V., 2022)
In this work, the environmental distribution of steroid compounds and the level of sewage-derived contamination were assessed using sterol ratios in the confluence area of two major rivers in the Serbian capital, where raw ...
Investigation of seasonal variations and multiple fuel options in a novel tri-generation CSP integrated hybrid energy process
(Elsevier Ltd, 2022)
This work presents a novel Mixed-Integer Non-linear Program (MINLP) that accounts for the presence of multiple fuels in tri-generation systems. The key novelty of this work pertains to the use of hybrid energy systems in ...
Effect of homogenization temperature on microstructure and mechanical properties of Al-Mg-Si alloy containing low-melting point elements
(Elsevier Ltd., 2022)
To evaluate the effect of homogenization conditions on the possible loss of low-melting-point Pb and Bi to the surface in the free-cutting AA6026 alloy, three homogenization regimes were applied: 480 degrees C/12 h, 530 ...
